You know that the population density of rabbits in an area is 80 individuals per square kilometer. The birth rate is 0.04 per week, and the death rate is 0.03 per week. From this information, population size would be calculated by

 A grassland is composed primarily of a single type of grass, with small amounts of three other grasses and several forbs. How will this species composition be likely to affect the function of this community?

An ecologist is studying changes in the abundance of plant species in a marsh as one moves away from the ocean. This means the ecologist is studying species changes that occur along a(n)

The largest estuary in the United States is the Chesapeake Bay, which extends through six states. The Bay is one of the most productive natural areas in the world. It is home to thousands of plants and animals, including many commercially important species. The water of the Bay is relatively shallow. Many areas are no more than 10 feet deep, with an average depth of 30 feet. Light penetrates the shallow water and supports submerged plants that provide food and shelter for the many species living in the bay ecosystem. However, like many estuaries, the Bay receives large amounts of fertilizer runoff from farms, lawns, and wastewater treatment facilities. Which is the most probable sequence of events when fertilizer runoff reaches the Bay?

If, over a long period of time, a region that is currently in the temperate seasonal forest biome becomes considerably colder, this region will most likely become
